Adnan Oktar, a creationist and rival of Richard Dawkins, has offered trillions of pounds to any scientists who can show proof of evolution.

Mr Oktar, 52, who successfully campaigned for Mr Dawkins' official website to be banned in Turkey, has said he will give 10 trillion Turkish lira, roughly equal to £4.4trn "to anyone who produces a single intermediate-form fossil demonstrating evolution."
